Abstract: A thermally controlled electric switching arrangement with a temperature controller, having a snap-action switch actuated by a bimetallic strip and of which the dead center position is displaceable by a manually operable setting device in order to influence the control point, and with a temperature limiter which is constructed as a melting metal fuse which comprises a fusible element, pressure elements engaging therein and at least one switching contact held in the closed position by the pressure element, so long as the limiter has not responded, is structurally simplified, the simplification also being intended to improve the variability of installation of the switching arrangement.

Abstract: A thermically controlled electrical switching element which is in the form of a temperature regulator or a temperature limiter. On a socket are arranged, in parallel orientation, a bimetallic spring plate, and a steel plate deflectable to both sides. The bimetallic spring plate is attached at its periphery in such a way that centrally, above a transition temperature, it can deflect in a first direction, and below a reverse transition temperature, it can deflect in a second, opposite direction. The steel plate attached at the rim together with the bimetallic spring plate, upon deflection of the spring plate, is also displaced in the first direction, and thereby, by means of a control element bearing upon its center, opens a switch contact interrupting the current flow to an electrical heating element.

Abstract: A temperature responsive switch has a bimetal-and-spring arrangement carrying a movable contact and having a first stable state urging the movable contact towards a stationary contact into an ON position and a second stable state urging the contacts away from one another into an OFF position; and a setting shaft setting the bimetal-and-spring arrangement to a desired temperature value at which the bimetal-and-spring arrangement displaces the movable contact from the ON position into the OFF position. The setting shaft has a relatively low temperature setting range and a relatively high temperature setting range. The switch further has a stopping mechanism having an operative and an inoperative state for preventing the bimetal-and-spring arrangement from assuming the second stable state in the operative state of the stopping mechanism and for allowing the bimetal-and-spring arrangement to assume the second stable state in the inoperative state of the stopping mechanism.

Abstract: A temperature sensitive switch has openable and closable electric contacts, a two-position bimetallic element and a two-position bistable element, both coupled to the contacts. At a predetermined maximum temperature, the bimetallic element moves from a first position to a second position and thereby opens the contacts and also moves the bistable element from a first position into a second position. The bistable element, in its second position, maintains the contacts open independently from the position of the bimetallic element, until the bistable element is reset from its second position to its first position, and thus the contacts are closed, by an external (manual) resetting force.
